USB/2-Track⚓︎

This is a tricky one, it depends on what I am needing.

Radio and PC Audio to Headphones/Speakers, and Mic to Headphones/Speakers⚓︎

This is the default setup. I can control the mic, radio, and speaker levels all independantly, while also being able to turn down Ctrl Rm and using the headphones for all my work.

Use caution with this setup as if you have the speakers plugged in, and the the levels too high, you will have feedback in both the headphones and the speakers.

  • To Phones/Ctrl Rm disabled
  • To Main Mix enabled
Radio and PC Audio to Headphones, PC only to Speakers, and Mic to Headphones Only⚓︎

This is the second most used config as it allows me to use the radios with my headphones or speakers, I can monitor the mic as needed, and if I take off the headphones I have normal PC usage for music.

Turning down the Phones/Ctrl levels will silence the speakers, and if I don’t need to monitor the mic I can turn those levels down as well.

  • To Phones/Ctrl Rm enabled
  • To Main Mix enabled
Radio to Headphones, PC to Speakers, and Mic to Headphones and PC⚓︎

This is the safest way to get mic audio to the PC as the mic does not come out the speakers. There is no chance of feedback.

  • To Phones/Ctrl Rm enabled
  • To Main Mix disabled
Radio to Headphones/Speakers, and Mic to Headphones/Speakers and PC⚓︎

Use caution with this setup as if you have the speakers plugged in, and the the levels too high, you will have feedback in both the headphones and the speakers.

  • To Phones/Ctrl Rm disabled
  • To Main Mix disabled
Mic to PC for recording⚓︎
  • To Main Mix must be disabled
